Figure 11-5.(A) Deflated tire flag, (B) Storage of valve core and cap using alternate deflated tire flag.LubricationYou should repack the bearings withMIL-G-81322 grease. Spread a thin layer of greaseon bearing cups. Inspect the rubber grease retainersfor evidence of deterioration. Inspect the felt greaseretainers for deterioration, contamination, or watersaturation. Replace them if necessary. Freshwater-saturated felt retainers may be dried and reused if theyare otherwise serviceable. Saltwater contaminatedfelt seals must be replaced. You should presoak feltretainers with VV-L-800 oil prior to their installation.Reinstall the wheel on the aircraft according to theapplicable maintenance instructions manual (MIM).InstallationWhen you reinstall the wheel on the aircraft, theproper adjustment of the bearings is extremelyimportant. The following general rules apply towheel installation:1. Tighten the axle nut while you spin the wheelwith your hand.2. When the wheel no longer spins freely, backoff the axle nut one castellation (one-sixth turn).When properly installed and adjusted, the wheel willturn freely, but will not move sidewise.NOTE: This procedure may vary from oneaircraft to another. Some aircraft require aspecific torque to be applied to the axle nut.In these cases, you should refer to theapplicable MIM.3. Install the appropriate axle nut safety device.4. Install and lock the hubcap in place.There are some inboard bearings that do not needto be removed except to be replaced. These bearingsare listed in table 3-2, Aircraft Wheels, NAVAIR04-10-1.Safety TrainingWhen you perform tire and wheel maintenance,you should handle inflated and partially inflatedwheel assemblies with the same respect and care aslive ordnance because of the destructive potential of agas under pressure.11-5
